siRNA mediated knockdown of NBS1 decreased the levels of phosphorylated Akt (pAkt Ser-473) and its downstream targets and IR increased the levels of NBS1 and phosphorylated Akt.
A. Western blot analysis showed that knockdown of NBS1 decreased the phosphorylated levels of Akt, GSK-3β, and Foxo1/3a). B. Ionizing radiation of two different cell lines (H1299, OCEM-1) increased the levels of NBS1 and phosphorylated Akt. C. Knockdown of NBS1 in H1299 cells abolished the increase in NBS1 and phosphorylated Akt levels under IR.
